I'm using the nRF52 Dev board and set the --rbp ALL option while using nrfjprog. It worked fine, and I am able to do OTA updates as I was testing the bootloader example. But the jlink is no longer recognized. I cannot undo the readback protection as I can no longer recognize the jlink on the board. I get the following error in keil: ***JLink Error: Communication timed out: Requested 20 bytes, received 0 bytes ! Could not transfer JTAG data. DAP error while reading DP-Ctrl-Stat register. Error: Flash Download failed - Target DLL has been cancelled
And I can't use any of the methods given here to disable the RBP: devzone.nordicsemi.com/.../
Has anyone seen this problem before? Any help would be appreciated, thanks!
